If you mean a number system analogous (similar) to our decimal system, the base for such a number system can be any integer, 2 or greater. In other words, the base can be 2, 3, 4, 5, etc. You need as many different digits as the size of the base (decimal is in base 10, so you need 10 different digits).
The number of digits in a number system is equal to the base of the system. The decimal system is base 10 and has ten digits. Binary has two bits, which is short for binary digits. Hexadecimal has sixteen digits (0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E & F), and so on.
-- The decimal system (base-10) uses 10 digits to write all numbers. -- The binary system (base-2) uses 2 digits to write all numbers.

Binary is base 2, using the digits 0 and 1. Decimal system is base 10 with 0-9.

There are infinitely many numbers in each system, however base 10 uses 10 digits {0, 1, 2, 3, 4, 5, 6, 7, 8, 9} and binary uses 2 digits {0, 1}. The maximum digit is one less than the base.
Binary is base 2, using the digits 0 and 1. Decimal system is base 10 with 0-9.
There are 10 digits in our number system. The symbols 0,1,2,3,4,5,6,7,8,and 9 are the digits used to create numbers.
This is just decimal, the number system that we usually use. Decimal means that there are 10 digits (0-9) as opposed to other number systems such as binary, which has only two digits.
It's a number system. For example, base 10 means that you have ten digits, 0 1 2 3 4 5 6 7 8 9, before you go to double digits (10). With base 2, you have only two digits, 0 1, before you go to double digits (10).
The duodecimal system, also known as base-12, is a numeral system that uses twelve as its base. It is similar to the decimal system (base-10) that we commonly use, but with twelve digits instead of ten. Some argue that a base-12 system could be more efficient than base-10 for certain calculations and measurements.
To the best of my knowledge (which is not completely inconsiderable), there is only one binary number system. That is the system in which each place is worth twice that of the preceding place, starting at 1. A 1 will count the place, a 0 will not. You may have meant how many number system are there 'like' the binary system, that is to say, how many number system are there which, like the binary system, do not use 10 digits. The answer to that is an infinite number. Binary is only special in that it uses the least possible number of digits. Our normal system (decimal) uses 10 digits (0-9). A number system can be made which uses any number of digits. The only three that I know of which are commonly used are the following. Decimal is our normal day to day number system with the digits 0-9. Binary is the number system used by computers and has only two digits, 0 and 1. Hexadecimal is a number system used by programs and has 16 digits, 0-f (that is, it uses 0-9 like normal, but continues by replacing "10" with "a", "11" with "b" and so on, up to "15" with "f"). To look into this more fully, they're called bases. Binary is base 2, decimal is base 10, and hexadecimal is base 16.
In base 2 system, also known as binary system, only the digits 0 and 1 are used. For example, the number 1011 in base 2 is equal to 11 in base 10. Another example is the number 1101 in base 2, which is equal to 13 in base 10.
